  • Publication number: 20080299597
    Abstract: The invention provides enzymatic methods for direct determination of percentage of glycated hemoglobin in blood samples without the need of a separated measurement of total hemoglobin content in blood samples. The methods utilizes one or two different types of oxidizing agents which selectively oxidize low-molecular weight reducing substances and high-molecular weight (mainly hemoglobin) reducing substances in blood samples, coupled with enzymatic reactions catalyzed by proteases, fructosyl amino acid oxidase. The amount of hydrogen peroxide generated in the reaction is measured for determination of percentage of glycated hemoglobin in blood samples. The invention provides kits for performing the methods of the invention.

  • Patent number: 6312141
    Abstract: The lamp assembly includes an emitting framework, a supporting ball, radiating levers and electronic-controller. The emitting framework is connected to the radiating levers via the supporting ball; the radiating levers to which explosion lamps and flashing lamps attach are bent into such a shape as to produce the effect of fireworks exploding; the electronic-controller is connected with firing lamps, explosive lamps and flashing lamp. The specially manufactured lamp assembly can effectively simulate the explosion process of fireworks controlled by electronic-control system.
